Two more people are now in custody in connection with a theft at Heathrow Airport where 21 people sustained injuries by a substance believed to be an irritant spray, according to police.
A 24-year-old man, was arrested in Lambeth on suspicion of robbery and assault and a 23-year-old woman was detained on suspicion of conspiring to commit a robbery. Both individuals remain in custody, authorities confirmed.
These detentions come after an investigation into an assault at the multi-storey car park at Terminal 3 this past Sunday. Prior to the incident, two women had stolen from them their luggage after getting out of a car park lift.
A toddler aged three was among the those hurt in the event. A total of five individuals went to hospital for treatment and have since been discharged.
Officers detained a man in his thirties for suspected theft and assault close to the scene. He was subsequently released under investigation while inquiries continue.
Police were called at approximately 8:10 in the morning GMT after reports came in regarding a number of people hurt by an irritating chemical believed to be an irritant spray.
The attack - an event that police said was a standalone incident and not considered terrorism - caused train delays and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 car park briefly.
